Disclosed in the present application is a base station. The base station comprises an array antenna and a baseband processing unit (BBU). The array antenna comprises n reception ports, n being a positive integer greater than 3. The array antenna is used for receiving uplink signals through m reception ports among n reception ports. The BBU is used for obtaining first uplink signals and second uplink signals, performing demodulation according to the first uplink signals and performing uplink scheduling according to the second uplink signals, the first uplink signals being uplink signals received through the m reception ports, m being a positive integer greater than q and is not greater than n, q is the number of downlink beams of the array antenna, and the second uplink signals being uplink signals obtained by performing digital forming on the first uplink signals according to a downlink directional diagram of the array antenna. By implementing the base station provided in the embodiment of the present application, the utilization rate of uplink performance of the antennas is improved; it is ensured that a cell in which a user equipment is located is not be strongly interfered, and accordingly there are available resources for scheduling.

The present invention provides an antenna beam reception processing method and apparatus, the method comprising: obtaining the downtilt angle of an active antenna inner beam, the downtilt angle of an active antenna outer beam and the downtilt angle of a passive antenna beam; when the downtilt angle of the active antenna inner beam, the downtilt angle of the active antenna outer beam and the downtilt angle of the passive antenna beam are judged to meet preset conditions, a cell covered by the active antenna outer beam using the active antenna outer beam and the passive antenna beam to perform four-antenna reception; or, a cell covered by the active antenna inner beam using the active antenna inner beam and the passive antenna beam to perform four-antenna reception. In the embodiment of the present invention, the cell covered by the active antenna inner beam or the cell covered by the active antenna outer beam can make use of four-antenna reception, therefore the uplink coverage area is broader and the uplink capacity is improved.

The invention discloses a method and a system thereof for realizing uplink power control in a feedback enhancement system of time division duplex, which applies a bidirectional spectrum and comprises the following processes: a base station alternatively distributes uplink time slots in a wireless frame of the bidirectional spectrum to different terminals or different terminal groups; each terminal or each terminal group obtains the uplink time slots with the same interval; the base station chooses a unidirectional spectrum of a downlink to transfer a feedback signal of power control to the terminals; a wireless frame on the unidirectional spectrum and that on the bidirectional spectrum keep synchronous; the terminals transfer uplink signals within the distributed uplink time slots to the base station; the base station finishes parameter estimation within a specific delay and transfers a feedback signal of power control to the terminals by adopting the unidirectional spectrum; the terminals receive the feedback signal of power control on the unidirectional spectrum and regulate power control of terminals, thus preparing for transferring the uplink signals within downlink-uplink time slots distributed for the terminals within the same wireless frame. The invention realizes sending down the feedback signal of power control with high frequency of which the period is shorter than the length of the frame; besides, the feedback delay is small, and the system throughput is increased.

The invention discloses an information transmission method and system used for improving uplink capacity, related to the field of communication. The information transmission method used for improvingthe uplink capacity comprises the following steps: a communication terminal uses a specified spread spectrum sequence to perform spectrum spreading on the uplink data to obtain spread spectrum information, and maps the spread spectrum information to a specified resource block for transmission, wherein all communication terminals located in the same set use the same resource block; and a receiver extracts transmission data from the specified resource block, and performs de-spreading on the transmission data with the corresponding spread spectrum sequence, so as to obtain the uplink data sent bythe communication terminal. The invention aims at the terminal characteristics of the mMTC scene of the 5G communication system, and the pseudo random sequence spread spectrum and the orthogonal frequency division multiplexing are combined, therefore, the existing resources are used more fully, the uplink capacity is greatly improved, and the reliability of uplink concurrent services of the maximum number terminals in the mMTC scene is ensured better.

The invention provides a method and a system for correcting errors of decoded data by using a UMTS (Universal Mobile Telecommunications System) receiver. The method comprises the following steps: A, performing CRC (Cyclic Redundancy Check) on convolutional decoded data; B, retrieving in a remainder table. The method and the system have the beneficial effects that the remainder table is constructed by using two significant features of a convolutional decoding error result, and a corresponding error mode is obtained, so that re-correction of the decoded data is realized, and the problem that the conventional UMTS receiver cannot be used for further correcting the data after a convolutional decoding error is solved. The method provided by the invention can be implemented in the form of hardware as well as the form of a software functional module, and is not limited to the combination of hardware and software of any form. Over 50 percent of error packets in convolutional decoding error data packets can be corrected on average, the voice quality and signaling reliability are improved greatly, and the uplink capacity of the system is increased.
